Composite material structure damage monitoring method and system

The invention discloses a composite material structure damage monitoring method and system. The structure damage monitoring method comprises the following steps of acquiring a response signal sample; according to a plurality of preset feature selection parameters, extracting a plurality of feature vectors of the response signal sample one by one, combining a plurality of feature vectors into a feature vector set, and normalizing the feature vector set to obtain a standard feature vector set; and inputting the feature vectors of the standard feature vector set into a pre-trained support vector machine classification model to obtain a classification result output by the support vector machine classification model. The method is advantaged in that composite material structure damage is monitored and analyzed based on the optimal path set and the trained support vector machine classification model, response signals of the initial health state, the slight damage state, the moderate damage state and the serious dam
